Add a ZLS command for installing a specific labelled version

[SuperAuguste]

As @leecannon said in zigtools/zls#1020 (comment), this is required for ZLS' new backwards compatibility model.

In essence, we would add a new "Install versioned release of ZLS" command which would allow someone to select a version from our releases page.

Once ziglang/zig#14475 is supported, this step could also be fully automated.

Installed a tagged version of zig, then zls, only to be nagged by the notification mentioned in the linked issue.
This is really sorely needed, automated or not

At some point in time, I started getting this message.

What am I supposed to do? At the very least there should be some documentation about how to use the extension. The average user (me) has no clue what's the "intended" way to use the extension. I suspect that the extension has automatically updated ZLS at some point? Most of us just use the latest stable release of Zig and we end up getting this version mismatch error.

For now I disabled zls update in vscode settings, then I have manually downloaded the 0.11 release and I have overwritten the zls executable downloaded by the extension.

I ended up downloading ZLS 0.11. The VS code extension has an option to set a path to a custom ZLS executable.
